Matthew 18:12

If a man have a hundred sheep. This is to shew the goodness and mercy of God towards sinners. By the one sheep, some understand all mankind, and by the ninety-nine, the angels in heaven. (Witham) --- Jesus Christ manifests his tender regard and solicitude for us poor weak creatures, by becoming himself the Son of man, thus abandoning in some measure the angels who are in heaven. He is come down upon earth to save by his death what was lost, imitating thus, with regard to men, the conduct themselves observe with regard to their sheep. (Bible de Vence) --- In the Greek, it is dubious whether the shepherd leaves the ninety-nine in the mountains, or, whether he himself goeth into the mountains in quest of the lost sheep.
